Back by popular demand! We've used these Acorn one-piece plastic frame and foundations in our own hives for years now. They work out nicely for us and you'll like them too! Although a little less rigid than a wood frame, they are still very durable and will last a long time in your apiary. With double wax coating for superior bee acceptance, these frames are a solid choice at a great price! Currently available in deep black and medium white.
